    Detex: The Leader in Alarmed Exit Hardware and Loss Prevention

    If you have a door that "Must Remain Closed" for security or fire code, you need Detex. Known globally for the "Big Red" Advantex and Value Series exit devices, Detex specializes in hardware that screams "Don't Open This Door." At Lock Depot, we provide the full suite of Detex alarmed hardware for retail back doors, restricted hospital zones, and airport security checkpoints.

    We stock the legendary Detex EAX-500 exit alarms and the V40 Series rim exit devices with integrated sirens. If you are dealing with employee theft or unauthorized egress, Detex is the only brand that combines Grade 1 durability with high-decibel audible alerts. We also carry Detex door propped alarms and weatherized kits for outdoor gate security.

    PRO TIP: Battery Maintenance is Key

    Detex exit alarms like the EAX-500 rely on 9V batteries. If your alarm is chirping, don't just pull the battery—that creates a security hole. We recommend a scheduled 12-month battery replacement cycle for all alarmed hardware to ensure your loss prevention system stays live 24/7.

    Detex hardware ships factory-sealed with full warranty included. We keep it stocked across our warehouses nationwide — order by 2 PM EST for same-day shipping.

    Detex Exit Hardware FAQ

    Is the Detex EAX-500 weatherproof?

    The standard model is for interior use. For outdoor gates, you MUST order the EAX-500W (Weatherized) version.

    How do I turn off the alarm on a Detex panic bar after an emergency?

    You need the control key (usually a standard mortise cylinder). Turning the key resets the alarm and re-arms the internal sensors.

    Can I get a Detex bar that delays the exit for 15 seconds?

    Yes, that is "Delayed Egress" hardware. Check out the Detex EasyKit solutions for a pre-configured delayed egress system.
